Overview

AAT2856 High Current Charge Pump with Dual LDO for BacklightApplications General Description The AAT2856 is a highly integrated charge pump with dual linear regulators optimized for systems powered from lithium-ion/polymer batteries.
The charge pump provides power for white LED backlight.
Six backlight LEDs can be driven at up to 30mA.
AnalogicTech's AS2Cwire™ (Advanced Simple Serial Control™) single-wire interface is used to enable, disable, and set the current to one of 32 levels for the backlight.
Backlight current matching is 1% for uniform display brightness.
The AAT2856 offers two high-performance lownoise MicroPower™ low dropout (LDO) linear regulators.
Both regulators use individual ...
